    bcm53xx: 6.6: fix ASM cache workaround linking
    
    Kernel 6.6 checks for orphan sections and prints a warning about them,
    which in turn will make CI fails as we have Werror enabled there.
    
    Issue is that cache-v7-min.S produces .init.text section which is an
    orphan section since it is not being handled by the vmlinux.lds.S linker
    script.
    
    So, lets put the generated .init.text section under .text.
    
    Fixes: f0d8ce4f482c ("bcm53xx: add testing support for kernel 6.6")
